4rotors

title says it all.

IF you are going to go this route, you had MIGHT as well stuff a 26b in it.

Not only will you keep it rotary powered, but you will have about 700NA HP on tap.

not another person. Ok i think everyone needs to stop and realize what they are saying! If ANYONE is going to replace an engine in an fd they better as hell put in some type of rotary. I know your just askin but its scary people even think like that. ahhhhhhhhhhh

4rotors

I would never put a piston engine into an Fd!!!!
I don't even have one yet to do that!!!!!
Jackass J/k .
Look at my User name, that should tell you something!!!!!!
When I do get my Fd I will try to make that happen!!!!!
I love what i'm am hearing about the rotary!!!!
Its small and powerful, the problem is not enough support.
If more manufactures where trying to design it, imagine what it could do.
All rx7's should have came with 20bs in the first place, and some people, wouldn't be talking ****!




P.S. I will also put a rotary engine in a C5 and Supra someday.

The RR Merlin V12 is too big to fit, sorry!

I know you can buy the Viper V-10 as a crate motor. I think it would sit in you lap if you tried to install it but hey nothings perfect!

I think a DE-tuned PT6 Turbine would do the trick. Probably the most dependable motor ever built, anywhere. About 600 shaft hp, would last a million hours without a tuneup, and would not blow water seals.
Add a canard wing up front, a bitchin' rear spoiler with a rudder and you could freakin' lift off!
There is of course the problem with price! about $250K.
The sound of that sucker spooling up would be worth it though........
AND BEST OF ALL - IT'S A ROTARY! (sort of):p

Seriously, you MAY be able to fit a small Ferrari V12, since they did make them as small as 3.5 liters. But for that kind of money you could have a 20B. I'm not quite sure how anyone would go about getting an R26B, but that would definitely overpower just about everything in the Rx-7.

You may as well just hit the car auctions and pick up a 787B itself.

Brad

The real question here is "WHY???" There is no answer to this question, however. There is ABSOLUTELY ZERO advantage to having a V-10 or V-12 in ANY RX-7. Power? No, you can get as much power as you could ever usefully use on the road from a 13B or 20B or even LT1. Weight distribution? FORGET ABOUT IT!! Out the window. Unless that is you can afford one of those $45,000 compact Ferrari V-12.

More I think about it, this is one of the stupidest posts I have ever read. I now feel dumber for having read it!

BrianK

I can't believe how ignorant people are even after the hundreds of well educated posts from JimLab. Do you people ever learn?

Anyway, an LT1 is pushing it and an LS1 is too big, I wish I knew the dimensions of some of the other options for engines, but I would doubt that they would be any smaller than the Chevy engines. Do you have a specific V-10 or V-12 in mind? Any reason you would prefer that over the proven LT1's (there are kits to fit an LT1 into an FD's engine bay without too much difficulty).

I'd like to see any rotary engine push 400 lb/ft torque at 2000 rpm on pump gas like JimLab's custom LT1. jeez people, get a clue. And the weight argument? Again - do your research. The *stock* LT1 in an RX is 50 lbs heavier than the stock 13B. BFD. Some of you are 50 lbs heavier than me, does that make my car handle or perform any better?... nope. 50lbs can be dealt with by an appropriate suspension setup and nothing else (and yes, that includes 50 lbs anywhere on the car).

oh well, no point in trying to enlighten the blissfully & persistantly ignorant.

mmaragos

Seemed like they were talking about the V10 or V12 being heavier, not the LT1 (which was mentioned in the same sentence as other potential engines 13B, 20b and LT1).

The only reason anyone would really want a V10 or 12 would be to say that you have a V10 or V12 in your FD (of course, the sound of a Ferrari V12 would be sweet...but you might as well get a used Testarossa - because a conversion using a Ferrari powerplant would cost you as much). I think the V10 or 12 would F/U the steering geometry and weight distribution significantly...I also think that you would get a lot more weight toward the nose. (Depending on which V10 or 12 you could get or use, it will likely be much longer than the LT1 or 20B.)

I respect the V8 conversion. It makes sense. Cost effective. High torque and horsepower capabilities. Similar weight. And enough have been done to work out the majority of problems associated with the swap. Hell, there is a kit that has most of "special" parts needed.

If you truly want a V10 or V12. I would think that your are going to need at least $100,000 to do the conversion right. If you have that, you will be able to find a shop that will start working on this project with you.

It took the 10th post to get some sort of answer.

However, there isn't a direct answer for this person's question. Just opinions on why, how much, and so forth.

To go along with Brian K, I don't think you can find a V-10 nor a V-12 that will fit in an FD engine bay without severe modification.

Good call man. I like that idea. The only problem is the cost and availability.

im4u

hey man ive looked into making a twin t78 viper engine.u can go to vipercarparts.com and get the engine and ecu for 7000 and a t56 tranny for 900 dollars.then u would have to massage the firewall back about 5 inches.remember its the same thing as 5.7l except with 2 extra pistons.or u can also lay the radiator flat and just keep the extra five inches forward, and get a special hood made.if i was u i would go with the special hood.cuz then u dont have to cut the fiewall or cut the drive shaft.if i had the money i was gonna do it believe me .its a sweet dream.but right now its easier to go with 2000 dollars everytime u blow a motor.but seriously maybe look into the 4rotor idea.go to pineappleracing.com

I dont feel like getting into another one of these threads so I think I'll just sit this one out.

JONSKI

I agree. It could just be me getting smarter, but these threads get more and more retarded every time I see them.

This is a dumbass post. Someone please delete it.

hey man sorry to steer ur thread off topic but i was wonder what type of engine an LS1 and LT1 were. R they rotory? What kind of HP, etc...?

thanks,
ok back to your original topic

They are both 350 V8's.

I hear you brother...

A STOCK LT1 compared to a STOCK 13B-REW is more than 50lbs different. You can't compare a stock 13B-REW with ac, emissions, etc to a bare block LT1 with no accesory pumps, injection, manifolds, etc and say they are both stock.

IIRC Jim's setup might be 50lbs heavier than a stock TT motor, but not 50lbs from a TT motor that doesn't have all the stuff on it (like his V8).

Jevv
Weigh them again...

Jeff

Freaky Monkey007

Hey jeff.. I hate to tell you but he is putting ac and everything on there.. Will be emissions legal.. If you have ever read any of his post you will see that its not just the block that he is saving weight on.. Everything internaly has been highly thought about for weight and high rpm's.. And if you think about it you cant have a high rpm motor and not have the internals weigh light as crap... Would be too much rotating mass...

jimlab

On no I won't.

My air conditioning was eliminated long before I ever thought about putting a V8 in the car, power steering is for Cadillacs, and emissions... well, who bothers passing emissions when they don't have to?

Jeff's right, my engine is about as stripped down as it gets. The alternator is the only accessory on the one drive belt, and there's no emissions equipment whatsoever.

OK, that part is true.

"They are both 350 V8's."

Actually the LS1 is a 346ci V8 (the new motors are metric). LS1 is found in cameroSS, firebird, and non-Z06 corvettes.
